Background and Objectives
In order to encourage students to save water at home, one of the IEP activities is Home Water Audit. Worksheets and water conservation tips are provided to help students fully understand how to save water at home, and to design effective water saving measures. It is hoped that the culture of water conservation can spread from schools to families.
Activity Details

Junior Level

  1. Record the date and water meter reading on the worksheet 7 days before the audit.
  2. Start the activity officially and record the starting date and water meter reading.
  3. The activity should be continued for 7 days. After the activity, record the date and water meter reading again.
  4. Calculate the volume of water used in the 7 days before the audit and 7 days after the audit, then compare the volume of water used during the two periods.
  5. Record the number of family members at home during the week of the activity.
  6. Record on the worksheet the water saving practices carried out every day during the week of the activity by every family member.
  7. After the end of the activity, write the thoughts about the activity on the worksheet.

Senior Level

Before conducting a Home Water Audit, senior primary students should first participate in and experience the School Water Audit activity. This will give them a better understanding of the significance and practice of the Home Water Audit.

Activity 1: Review of Water Efficiency of Household Devices

  1. Measure the amount of water used in 3 - 5 seconds for the taps in the kitchen, bathroom, as well as showerheads in the bathrooms.
  2. Convert the data to water consumption in 1 minute, and compare it with the water consumption of different grades in the Water Efficiency Labelling Scheme (WELS)*.
  3. Check whether home appliances (e.g. washing machine) are WELS-listed products.
  4. Examine whether home appliances and pipes have any leaks, and find out ways to improve.

Activity 2: Review of Daily Water Use Habits at Home

  1. Find a previous water bill (or more than one) to review water consumption in the past. Write your account number onto the worksheet.
  2. Plan water conservation measures at home.
  3. Review whether the water consumption is reduced because of water conservation measures.
